This is a list of earthquakes in Japan with either a magnitude greater than or equal to 7.0 or which caused significant damage or casualties. As indicated below, magnitude is measured on the Richter magnitude scale (ML) or the moment magnitude scale (Mw), or the surface wave magnitude scale (Ms) for very old earthquakes. The present list is not exhaustive, and reliable and precise magnitude data is scarce for earthquakes that occurred prior to the development of modern measuring instruments.

changing of the Ariake Sea coastline, in the center of Mount Unzen, Kumamoto Prefecture (right) and the Amakusa Islands (see below) were affected by the tsunami
An earthquake caused by volcanic activity of Mount Unzen (in the Shimabara Peninsula Nagasaki, Japan). It killed all 15,000 people altogether, due in large part to a huge tidal wave that was triggered by the collapse of nearby Mount Mayuyama's southern flank into the bay. The incident is also referred to with the phrase 'Shimabara erupted, Higo affected' (岛原大変肥后迷惑), as many people in Higo, (Kumamoto, located 20 km away across the Ariake Sea) were also killed by the resulting tsunami, which then bounced back to hit Shimabara again.[21]

Records from the time indicate 6,641 deaths inside the city and 2,759 injuries; much of the city was destroyed by fire, leading many people to stay in rural inns. Aftershocks continued for twenty days.[23]

September 1, 1923 8.3 ML 1923 Great Kantō earthquake 大正関東地震
Taishō Kantō Jishin
(Kantō Daishinsai)
Izu Ōshima 142800 142,800[30] An earthquake which struck the Kantō plain on the Japanese main island of Honshū at 11:58 on the morning of September 1, 1923. Varied accounts hold that the duration of the earthquake was between 4 and 10 minutes. The quake had an epicenter deep beneath Izu Ōshima Island in Sagami Bay. It devastated Tokyo, the port city of Yokohama, and the surrounding prefectures of Chiba, Kanagawa, and Shizuoka, and caused widespread damage throughout the Kantō region.[31] The power and intensity of the earthquake is easy to underestimate, but the 1923 earthquake managed to move the 93-ton Great Buddha statue at Kamakura. The statue slid forward almost two feet.[32] Casualty estimates range up to about 142,800 deaths, a figure including approximately 40,000 who went missing and were presumed dead.
May 23, 1925 6.8 ML 1925 Kita Tajima earthquake 北但馬地震 Kita Tajima Jishin Toyooka in Hyogo Prefecture 000428428 This earthquake's epicenter was (35.6 degrees north latitude, 134.8 degrees east longitude), in the Maruyama River estuary.

This quake caused extensive damage to the town of Toyooka and the Maruyama River area. Just before the shaking could be felt, a sound like a cannon was reportedly heard intermittently from the direction of the estuary near the Maruyama River. During the earthquake, the ground in the town of Tokyooka experienced strong seismic vibrations for 16 seconds. As most of the buildings of the time were wooden, many of them were destroyed at once during the initial earthquake. In the fire that broke out subsequently, half of Toyooka was burned down, with many deaths resulting (a reported 8% of the town's population.) 272 deaths were confirmed to have occurred in the Kinosaki area.

The Tottori earthquake had its epicenter offshore from Ketaka District, now part of Tottori city, with a magnitude of 7.2 on the Richter Scale. The magnitude of the earthquake was 6.0 in Tottori city, and 5.0 as far away as Okayama on the Inland Sea.[36]

On the Moment Magnitude scale, its magnitude measured 8.1, at it was felt at a maximum intensity of 5 on the Shindo scale (or VII, "Severe", on the Mercalli intensity scale). It struck the provinces along the coast of the Tokai region, causing serious damage and triggering a tsunami. The earthquake and tsunami combined killed 1,223 people, with injuries reported to have affected 20,000 people or more.[37]
January 13, 1945 6.8 ML 1945 Mikawa earthquake 三河地震 Mikawa Jishin Mikawa Bay 0011801180 + 1126 missing An earthquake which occurred off Mie and Aichi prefectures, Japan at 03:38 on January 13, 1945. As the earthquake occurred during World War II, information about the disaster was censored, and efforts at keeping the disaster secret hampered relief efforts and contributed to a high death toll.[38] The Mikawa earthquake had its epicenter offshore in Mikawa Bay (34°42.1′N 137°6.8′E / 34.7017°N 137.1133°E / 34.7017; 137.1133 at a depth of eleven kilometers).

The earthquake began on Tuesday, August 16, 2005, and affected Japan's northeastern coast. It triggered a tsunami warning, and buildings shook 200 miles away in the capital, Tokyo. It was initially estimated to have a rating of 6.8., and the U.S. Geological Survey later registered it as a 7.2.[53]
November 15, 2006 8.3 Mw 2006 Kuril Islands earthquake 2006年千島列島沖地震 Nisen-roku-nen Chishima Rettō Oki Jishin Kuril Islands about 160 km (99 mi) due east of the southern tip of Simushir in the Kuril Islands 0000000 The earthquake happened at 20:29 JST on November 15, 2006, causing a tsunami to hit the Japanese northern coast.
January 13, 2007 8.1 Mw 2007 Kuril Islands earthquake 2007年千島列島沖地震 Nisen-nana-nen Chishima Rettō Oki Jishin 46°28.8′N 154°04.48′E / 46.4800°N 154.07467°E / 46.4800; 154.07467 0000000 The earthquake happened at 1:23 p.m. JST (04:23 UTC) and resulted in a tsunami warning but did not cause significant damage.[54] The epicentre was located 95 km to the south east of the 2006 Kuril Islands earthquake that struck a few weeks earlier.
March 25, 2007 6.9 Mw 2007 Noto earthquake 能登半島地震 Noto Hantō Jishin Ishikawa Prefectureabout 11 km (6.8 mi) due west of the southern end of the town of Wajima 0000011 At 9:42 a.m., a magnitude 6.9 earthquake, struck the Hokuriku region of Japan, near the Noto Peninsula. The earthquake shook the city of Nanao and the town of Anamizu with a seismic intensity of 6+ on Japan's shindo scale. One death, in the city of Wajima, and at least 214 injuries have been reported. A tsunami advisory was immediately made for the Kaga coast and Noto coast, and a 10–20 cm wave hit shore about 30 minutes later.[55]
July 16, 2007 6.6 Mw 2007 Chūetsu offshore earthquake 新潟県中越沖地震 Niigata-ken Chūetsu Oki Jishin Niigata Prefectureabout 29 km (18 mi) west of Niigata 00001111 The earthquake[56]) was a powerful magnitude 6.6 earthquake[57][58] that occurred 10:13 a.m. local time (01:13 UTC) on July 16, 2007, in the northwest Niigata region of Japan. The earthquake shook Niigata and neighbouring prefectures. The city of Kashiwazaki and the villages of Iizuna and Kariwa registered the highest seismic intensity of a strength 6 on Japan's shindo scale, but the quake was felt as far away as Tokyo.[57] Eleven deaths and at least 1,000 injuries have been reported, and 342 buildings were completely destroyed, mostly older wooden structures.[57][59][60]
June 14, 2008 6.9 Mw 2008 Iwate–Miyagi Nairiku earthquake 岩手・宮城内陸地震 Iwate Miyagi Nairiku Jishin Iwate Prefectureabout 1 km (0.62 mi) east of Narusawa Onsen in northwest Iwate Prefecture 00001212 This earthquake struck the central Tōhoku region, in northeastern Honshū, Japan.[61]
